The 2nd edition of Research.com ranking of the best researchers in the
discipline of Medicine relies os data
consolidated from various data sources including OpenAlex and
CrossRef. The bibliometric data for evaluating the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
takes into account only publications and citation
values for an examined discipline.
The scope of our Medicine research
Our best scientists ranking is a reliable lineup of leading scholars from the field of Medicine, based on a detailed analysis of 166,880 researchers discovered from multiple bibliometric data sources. For the field of Medicine, as many as 68936 researchers were analysed.
What is D-index approval threshold for Medicine
The D-index threshold for including a researcher to be examined is placed at 70 if the majority of of their publications are in the discipline of Medicine. The acceptance requirements for scientists to be considered into the ranking of top researchers are based on the D-index, proportion of the publications made within the specific discipline as well as the awards and achievements of the scholars. The D-index threshold for considering top researchers is set as an increment of 10 depending on the total number of scholars estimated for each area od study whilst ensuring that the top 1% of leading researchers are added into the ranking. We expect a proximity of 30% or less between a scientist’s general H-index and their D-index.
Other verification methods
Since our primary goal is to ensure that only genuine scientists are listed in Research.com ranking we realize that raw data are never meant to be a complete tool to evaluate the contributions of scholars. For that reason we manually verify every profile and cross-correlate it against publications in a wide range of reliable sources. Even though it’s not a metric contributing to a researcher’s position in the ranking, the number of papers published in well-known journals and conference proceedings should form a valuable secondary signal of their contribution to research in a selected discipline. Position in the ranking is established using each scientist’s D-index using metrics compiled from OpenAlex and CrossRef, which are the most credible and well-established bibliometric databases of this kind available to the scientific community. A detailed explanation of our research procedures can be found on our methodology page.
Our aim is to motivate scholars, companies and politicians worldwide to investigate where leading experts are heading and to provide a way for the whole scientific community to find out who the leading experts in specific fields of research, in various countries, or even within research institutions are.
